Title: Production of high carbon steel with fine pearlitic structure
Inventor: KUROKI TOSHIYA
IPC: B21B1/16
Filed: 1994-08-03
Abstract: PURPOSE:To produce a steel with a fine structure high in toughness and ductility by subjecting a carbon steel or a low allay steel having a specified carbon content to rough rolling under specified conditions, immediately cooling the steel surface to a specified temp., recuperating the steel surface and thereafter executing rolling. CONSTITUTION:The slab 6 of a carbon steel contg. 0.6 to 1.0% C is heated to >=1050 deg.C by a heating furnace 5, is subjected to a final pass at 1050 to 1100 deg.C by a rough rolling line 1 and is formed into an intermediate material. Immediately after that, the steel surface is cooled to a temp. lower by 50 to 200 deg.C by a rapid water cooling table 2, is thereafter recuperated by a recuperating table 3 till the temp. of the whole body is uniformized and is subjected to finish rolling 4. By this method, a certain measure of the refining of the structure is executed by the rough rolling, and the target gammagrain size is obtd. while loads in the finish rolling is reduced, so that the high carbon steel with a fine pearlitic structure can efficiently be produced. Carbon forms a pearlitic structure and is effective for the improvement of the wear resistance of a steel for a rail in particular. For obtaining the same structure, the lower limit or above is required, but in the case of the upper limit or above, its ductility is deteriorated.

Title: Optical transmitter
Inventor: KITAYAMA TADAYOSHI
IPC: H04B10/50
Filed: 1984-09-03
Abstract: PURPOSE:To prevent generation of background light due to naturally irradiated light from a laser diode by adding a switch means operated synchronously with a transmission request signal in an optical transmitter transmitting intermittently data. CONSTITUTION:Transmission data 2 is applied to a transistor (TR)16 synchronously with a transmission request signal 15. The TRs 16, 17 form a current changeover switch. When the request signal 15 reaches a threshold voltage 18 of the TR17, an output current of a current amplifier 5 is outputted to the laser diode 4 as a bias current 6 via the TR16. On the other hand, when the request signal 15 reaches a voltage 18 or below, the output current of the amplifier 5 is outputted to a load 19 via the TR17. Through the operation above, no current flows to the diode 4 at all at the non-transmission system, then no background optical output light due to naturally irradiated light is caused.

Abstract: PURPOSE:To provide the titled raw pitch which has a relatively low softening point and easily forms a mesophase, by adding a nucleus-hydrogenated product of a bicyclic or tricyclic arom. hydrocarbon to coal tar, and heat-treating the mixture under specified conditions. CONSTITUTION:100-200pts.vol. nucleus-hydrogenated product of a bicyclic or tricyclic arom. hydrocarbon such as tetralin is added to 100pts.vol. coal tar from which quinoline-insoluble matters have been removed.

Title: Bearing arrangement using roller bearing and manufacture of part thereof
Inventor: RONARUDOUSU YOHANESU FUAN BURA
IPC: B21B31/07
Filed: 1994-08-04
Abstract: PURPOSE: To avoid temperature fluctuations at contact surfaces so as to extend the life of a bearing arrangement in which bearings make contact with one another by covering one of at least two adjacent opposite contact surfaces with a friction-reducing layer. CONSTITUTION: Roller bearings 6, 6' have inner race rings 8, 8' and a double taper roller bearing 7 has an inner race ring 11, with the inner race rings 8, 11 making contact with each other at contact surfaces 16, 16', and with the inner race rings 11, 8' making contact with each other at contact surfaces 17' 17. One of each of the opposite pairs of contact surfaces 16, 16' and 17, 17' is provided with a friction-reducing layer which is 0.2 to 0.5 mm. The friction-reducing layer is applied by heat spraying, such as plasma spraying or wire spraying, and the material applied is bronze or molybdenum. The friction-reducing layer lengthens the time during which slip between the different contact surfaces occurs, and less heat is generated per unit time.  Consequently, temperatures at the contact surfaces do not rise quickly and the occurrence of microcracks is avoided or delayed to extend the operational life of a bearing arrangement.

IPC: F16H7/12
Filed: 1989-07-18
Abstract: PURPOSE: To operate a tensioning device constantly with a member easily to be manufactured for a long driving time by arranging plural rolling element so that they can roll along an inclined face in a trough between an inner ring fixed to a swivel arm and an outer ring in contact with a lining. CONSTITUTION: During the period of turning a swivel arm 12, the motion of an inner ring 9 is transmitted to an outer ring 10 through a rolling element 11 and a spring 13, and the outer ring 10 slides along a friction lining 12 which performs friction damping action. Further, when the swivel arm 2 moves in the opposite direction to the direction in which a belt is tensed, the rolling element 11 rolls toward the outer end part of an inclined face 15, and is pressed so that the inner ring 9 and the outer ring 10 axially move away from each other. As a result, a normal acting on the lining 12, therefor friction damping action is increased. Furthermore, when the arm 2 moves in the reverse direction, namely in the direction in which the belt is tensioned, the rolling element 11 return-rolls into the trough 14 along the inclined face 15.  In this case, the normal acting on the lining 12, therefore the friction damping action is decreased.

CONSTITUTION:An ultrasonic wave motor is composed of an oscillating section and a moving section. So far as the oscillating section is concerned, on the surface of a sheet piezoelectric unit 1, an oscillating unit 2 is bonded and fixed, and so far as the moving section is concerned, on the working side surface of a moving unit 3 as a main unit, a frictional material layer 4 made of plastics is fixed, and the surface is coated with lubricant 5 to be composed and is permitted to come in pressure contact with the surface of said oscillating unit 2. Then, by applying the high frequency electric-field of ultrasonic wave frequency to the piezoelectric unit 1, the progressive wave of ultrasonic wave oscillation is generated on the piezoelectric unit 1 and oscillating unit 2. In this case, the frictional material layer 4 at the moving section in contact with the oscillating unit 2 and the wave front section of the progressive wave is driven by a frictional force between the layer 4 and the oscillating unit 2, and if a power source is interrupted during the driving, this frictional works as a braking force.
